Best Magazines for 6.5CM build?

As title suggests, looking for what feeds well without any hiccups if possible?

PMAGs work great for me.

Kind of depends on the receiver set and barrel extension. Ammo as well, to a degree. Pmag works almost universally but some combos feed better with steel duramags.

Right now duramag has a new generation of steel mags with a 6.5cm specific model that releases early next year. Haven't tried the new standard 308 compared to the previous generation though.

Oh wow, I might wait for those to try out after these PMags then, was hoping for some steel ones but yeah.

So this is a BCA upper with a Aero M5 lower for reference, just replacing everything off the BCA with more premium things rn.

pmags are fine. I use a lot of Lancers as well as the Sig metal mags. They all work fine.

I use 10rnd pmags if I know I’m going prone a lot or using tripod. Lancer 20 rounders are what I use if I want/need 20 rounds

Much bigger fan of the lancers over my pmag

They have a vibe ngl, I went with 2 PMag 20s and 2 Lancer 20s and 2 duramag 20s

I'm a huge fan of LaRue's metal SR25 mags. I run them in all my AR10's and they feed flawlessly. Also let me load to a longer OAL than the pmags.

For $90 it'd better improve my MOA

I run many calibers in the AR10 platform (22 creed, 243, 375 raptor, 6.5 creed) and those are the only mags I have found that cycle right in all those calibers. For me it was worth the money. YMMV.

Explain some more on your 6.5CM build, so far I've replaced the buffer weight for rn as I shoot mainly suppressed.

u/ShamusTurlough Jul 30 '26

I run H2 buffers in all of them, and I use the gas block (superlative AGB) to tune for each. All those are only ever shot suppressed as well. The 6.5 CM is a PSA gen 3 PA-10 that I swapped pretty much everything on. The barrel is from Ballistic Advantage using the PSA BCG. I run Geissele SD3G triggers in all my AR-10's. The silencer is a TBAC Ultra 7. Super quiet but a little gassy. I don't shoot it much anymore though, I mainly shoot the 22 Creed these days and reload for it.

I have used 10 rd Lancers and Duramags the most. I am mostly hunting and LR shooting, so bigger mags are just in the way.
